Description

Technical Field

[0001] The invention relates to the technical field of freeze-dried food processing, in particular to an energy-saving pulverizing device for freeze-dried food processing. Background Art

[0002] Food freeze dryer is also called food vacuum freeze dryer, food freeze dryer, food freeze drying equipment. It can be used for vacuum freeze drying of meat, vegetables, fruits, aquatic products, milk, beverages, soups, health products, Chinese medicinal materials and other types of food. Freeze-dried food meets the requirements of naturalness, nutrition and convenience. In the food processing industry, freeze-dried food is favored because of its unique advantages. Freeze-dried food is quickly frozen and vacuum ice-dehydrated to preserve the original color, aroma, taste, nutritional components and appearance of the original material, and has good rehydration properties. It does not contain any additives and is an ideal natural and hygienic food. In food processing, the food is first freeze-dried and then crushed to obtain a granular state of the food to increase the quality of subsequent food processing.

[0003] Most existing energy-saving freeze-dried food pulverizing devices pulverize by grinding. During the pulverizing process, the freeze-dried food is placed between two grinding blocks, and the pulverization of the freeze-dried food is achieved by the mutual movement of the two grinding blocks. However, during the grinding process, the ground freeze-dried food is still between the unground freeze-dried food. Therefore, during the grinding process, the ground freeze-dried food will prevent the unground freeze-dried food from contacting the grinding blocks, thereby reducing the grinding rate. Summary of the Invention

[0017] Compared with the prior art, the present invention has the following beneficial effects:

[0018] 1. The sliding assembly, the movable housing, the pressing assembly, and the grinding plate cooperate with each other to grind the food placed inside the movable housing. Then, the scraper, the connecting rod, the first spur gear, the first rack rod, and the movable assembly cooperate with each other to drive the grinding plate in the mounting hole to flip 180 degrees, thereby flipping the ground food on the grinding plate into the cavity and dropping it into the cavity, separating the ground food from the unground food, preventing the ground food from interfering with the unground food from contacting the grinding plate, thereby increasing the grinding rate.

[0019] 2. The ground food is pushed into the guide hole opened in the rectangular block by the scraper. Then, through the cooperation of the supporting block, vertical rod, elastic component, top rod, limit rod and guide plate, the ground food can be automatically put into the mobile shell again. Through the repeated movement of the mobile shell, the food is ground multiple times until the food is ground to the required coarseness.

[0020] 3.

The structure is compact and easy to operate.

[0021] 4. When the top block releases the lock of the locking assembly, the vertical rod drives the support plate to move upward under the action of the elastic assembly. At the same time, when the support plate moves upward, it is in a state of tilting toward the filter hole, so that the ground food on the support plate can contact with the filter hole, so that the food that reaches the required coarseness can pass through the filter hole, which plays the role of automatic feeding. The food that does not reach the required coarseness is put into the movable shell again;

[0022] 5. When the support plate drives the ground food to move upward in the guide hole, the support block, the second spur gear, the second rack rod, the rotating rod and the multiple arc plates cooperate with each other to drive the food above the support plate to rotate continuously, so as to prevent the food with larger particles from staying on the side close to the filter hole and blocking the other food with the required coarseness and fineness from passing through the filter hole, so as to facilitate the food with the required coarseness and fineness to pass through the filter hole;

[0023] 6. Under the action of the support rod and the first triangular block, when the mobile shell moves to the rectangular block, it automatically drives the slide rod and the pressing plate to move upward, thereby ensuring that the food entering the mobile shell from the guide hole can fall under the pressing plate and fall above the unground food. The structure has a high degree of automation and is easy to operate. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0035] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0036] Reference Figures 1-10An energy-saving pulverizing device for freeze-dried food processing includes a base 1, a cavity is opened inside the base 1, a plurality of mounting holes connected to the cavity are opened on the upper surface of the base 1, a rotating shaft 2 is rotatably installed in the plurality of mounting holes, a grinding plate 3 is fixedly sleeved on the rotating shaft 2, and a plurality of grinding blocks 44 are fixedly installed on the upper surface of the grinding plate 3.

[0037] The grinding plate 3 is parallel to the surface of the base 1. When the food is slid along the upper surface of the base 1, the food will come into contact with the multiple grinding blocks 44 on the grinding plate 3, thereby crushing the food into multiple fine particles and leaving them between the grinding blocks 44 and the grinding plate 3. When the food comes into contact with the grinding blocks 44 multiple times, it will be ground into even finer particles.

[0038] A moving shell 4 is slidably installed on the base 1 through a sliding assembly. The sliding assembly includes a slide rail 9 symmetrically fixedly installed on the base 1 and two sliders 10 respectively slidably sleeved on the two slide rails 9. The moving shell 4 is fixedly installed between the two sliders 10. The other end of the connecting rod 6 is fixedly connected to the slider 10. A pressing assembly for pressing food is provided in the moving shell 4. Strip holes connected to the cavity are opened on both sides of the base 1. A scraper 5 is horizontally slidably installed in the cavity. Connecting rods 6 are fixedly installed at both ends of the scraper 5. One end of the connecting rod 6 passes through the strip hole and is connected to the sliding assembly. A first rack bar 7 is horizontally slidably installed on the upper end of the cavity. A first spur gear 8 is fixedly sleeved on multiple rotating shafts 2. Multiple first spur gears 8 are meshed with the first rack bar 7. The first rack bar 7 is provided with a moving assembly for driving the first rack bar 7 to move.

[0039] The slider 10 and the slide rail 9 support the movable shell 4, ensuring that the movable shell 4 can slide horizontally on the base 1. When grinding food, the food is placed in the movable shell 4. Under the action of the pressing component, the food contacts the upper surface of the base 1. During the movement of the movable shell 4, the scraper 5 in the cavity will be driven to move through the two connecting rods 6. When the first rack rod 7 moves horizontally, it will drive multiple first straight gears 8 to rotate, and then drive the grinding plate 3 to rotate 180° through the rotating shaft 2, so that the ground food on the grinding plate 3 falls into the cavity.

[0040] A moving hole is provided on the upper surface of the moving shell 4, and the pressing assembly includes a sliding rod 11 vertically slidingly installed in the moving hole, a pressure plate 12 slidingly arranged in the moving shell 4, a first telescopic spring 13 sleeved on the sliding rod 11 and a transmission component for driving the sliding rod 11 to move vertically upward, one end of the sliding rod 11 is fixedly connected to the pressure plate 12, and the two ends of the first telescopic spring 13 are respectively fixedly connected to the surface of the pressure plate 12 and the inner wall of the moving shell 4, a first transmission hole is provided on the surface of the sliding rod 11, and the transmission component includes a support rod 14 fixedly installed on the base 1 and a first triangular block 15 fixedly installed at one end of the support rod 14, and the height of the first triangular block 15 is greater than the length of the first transmission hole.

[0041] Under the action of the elastic force of the first telescopic spring 13, the slide rod 11 tends to move vertically downward. In the initial state, one end of the first triangular block 15 is inserted into the first transmission hole opened on the slide rod 11, and the pressure plate 12 is located at the uppermost end in the movable shell 4, so as to facilitate the input of food into the movable shell 4 and directly below the pressure plate 12. When the first triangular block 15 is separated from the slide rod 11, under the action of the elastic force of the first telescopic spring 13, the pressure plate 12 will squeeze the food to contact the upper surface of the base 1.

[0042] The moving assembly includes a mounting block 16 fixedly mounted on one end of the first rack rod 7, a positioning rod 17, a first spring rod 18 fixedly mounted on the positioning rod 17, a second triangular block 19 slidably mounted on the lower surface of the first rack rod 7 and an L-shaped push rod 20 fixedly mounted on the other end of the first rack rod 7. A sliding hole is provided on the surface of the mounting block 16, and the positioning rod 17 is slidably mounted in the sliding hole. The other end of the first spring rod 18 is fixedly connected to the mounting block 16, a positioning groove is provided at the upper end of the cavity, one end of the positioning rod 17 is inserted in the positioning groove, a second transmission hole is provided on the surface of the positioning rod 17, one end of the second triangular block 19 is inserted in the second transmission hole, and the scraper 5 is located between the push rod 20 and the second triangular block 19.

[0043] In the initial state, under the action of the elastic force of the first spring rod 18, one end of the positioning rod 17 is inserted into the positioning groove, thereby limiting the movement of the first rack rod 7. When the scraper 5 moves, it will contact the second triangular block 19 and insert the second triangular block 19 into the second transmission hole, driving one end of the positioning rod 17 to be removed from the positioning groove, thereby releasing the lock on the first rack rod 7. When the scraper 5 contacts the push rod 20 installed at the other end of the first rack rod 7, it will drive one end of the positioning rod 17 to be inserted into the positioning groove, which plays a locking role again.

[0044] The surface of the base 1 is provided with a fixing hole connected to the cavity, and a rectangular block 21 is fixedly installed in the fixing hole. A U-shaped guide hole is provided on the surface of the rectangular block 21, and a guide plate 22 is fixedly installed on the upper end of the guide hole. The lower end of the guide hole is located in the cavity. A guide block 43 with a right-angled trapezoidal cross section is symmetrically fixed on the surface of the scraper 5. The width of the rectangular block 21 is less than the width between the two guide blocks 43. A through hole is symmetrically provided on the upper end of the rectangular block 21. Vertical rods 23 are vertically slidably installed in the two through holes. One end of the two vertical rods 23 is provided with an elastic component, and the other end is rotatably installed with a moving block. Supports are slidably installed on the two moving blocks. Plate 24, two limit rods 29 are vertically fixedly installed in the diversion hole, the sliding connection points of the two limit rods 29 and the two moving blocks and the support plate 24 are all located on the same side of the center line of the support plate 24, and the two vertical rods 23 are both obliquely fixedly installed with a top rod 25, and the two vertical rods 23 are horizontally fixedly installed with a cross bar 26, and the cross bar 26 is provided with a locking assembly for locking the cross bar 26, and a pull rope 27 is fixedly installed on the cross bar 26. A guide wheel 28 is rotatably installed in the diversion hole, and one end of the pull rope 27 passes through the guide wheel 28 and is fixedly connected to the scraper 5. A return port is provided on the surface of the movable shell 4, and the return port and the guide plate 22 are on the same horizontal plane.

[0045] During the movement of the scraper 5, the cross bar 26 will be pulled by the pull rope 27, thereby driving the support plate 24 to move vertically downward. When the scraper 5 moves to the end of the base 1 farthest from the rectangular block 21, the support plate 24 is also moved to the lowest end of the guide hole. At the same time, the locking assembly just locks the cross bar 26. When the scraper 5 moves back, it will push the ground food in the cavity into the guide hole and accumulate above the support plate 24.

[0046] The width of the support plate 24 is slightly larger than the width of the guide hole. When the support plate 24 moves up and down in the guide hole, under the action of the top rod 25, the support plate 24 is in an inclined state, and the two sides of the support plate 24 just slide in contact with the inner wall of the guide hole. When the support plate 24 contacts the limit rod 29, the support plate 24 will tilt in the other direction, so that the food on the support plate 24 will slide onto the guide plate 22 and fall into the movable shell 4.

[0047] The elastic component includes a round block 30 fixedly mounted on one end of the vertical rod 23 and a second telescopic spring 31 sleeved on the vertical rod 23. The two ends of the second telescopic spring 31 are respectively fixedly connected to the upper end of the rectangular block 21 and the round block 30. Under the action of the elastic force of the second telescopic spring 31, the vertical rod 23 drives the support plate 24 to move vertically upward.

[0048] A lock hole connected to the guide hole is provided on the surface of the rectangular block 21. The locking assembly includes a second spring rod 32 fixedly mounted on the cross bar 26 and a trapezoidal block 33 fixedly mounted at one end of the second spring rod 32. One end of the trapezoidal block 33 is inserted into the lock hole. A top block 34 is fixedly mounted on the scraper 5. The top block 34 and the lock hole are in the same horizontal plane. When the scraper 5 drives the food to move into the guide hole, the top block 34 will be inserted into the lock hole, and the lock assembly will be released from the cross bar 26 through the top block 34.

[0049] A plurality of filter holes connected to the diversion holes are provided on the side of the rectangular block 21. A collection box 35 is placed on the base 1. The collection box 35 is located below the plurality of filter holes. Support blocks 36 are symmetrically fixedly installed on the support plate 24. An elliptical hole 42 is provided on the surface of the two support blocks 36. A rotating rod 37 is rotatably inserted on the two elliptical holes 42. A plurality of arc plates 38 are fixedly installed on the rotating rod 37. Slide grooves 39 are symmetrically provided on the inner wall of the diversion hole. The two ends of the rotating rod 37 are respectively inserted in the two slide grooves 39. A second spur gear 40 is fixedly sleeved on the rotating rod 37. A second rack rod 41 is vertically fixedly installed on the inner wall of the diversion hole. The second spur gear 40 is meshed with the second rack rod 41.

[0050] The rotating rod 37 can move vertically up and down in the slide groove 39. At the same time, the rotating rod 37 is rotatably installed on the support plate 24 through two support blocks 36. When the support plate 24 rotates, under the action of the elliptical hole 42, the rotating rod 37 and the support plate 24 move relative to each other, and under the action of the second spur gear 40 and the second rack rod 41, the rotating rod 37 can drive the multiple arc plates 38 to rotate.

[0051] The size of the filter hole is the same as the standard size of the ground food. When the support plate 24 drives the ground food through the filter hole, the food that reaches the required coarseness will pass through the filter hole and be collected in the collection box 35, while the food that does not meet the standard will enter the movable shell 4 for further grinding.

[0052] In the present invention, the FZG series freeze dryer adopts standardized production, which is suitable for processing and producing various types of food, Chinese herbal medicine, and industrial raw materials. It adopts high-quality materials and imported configurations of major components that are widely accepted in the industry. At the same time, it adopts high-tech manufacturing processes. The equipment fully complies with GMP standards. In the present invention, when freeze-drying food, the freeze dryer used adopts the imported brand Omron PLC control system, which is convenient for storing data and easier to master operation. It has automatic / manual control modes, and the control mode can be switched arbitrarily. The process settings can be set in multiple groups. The formula can be modified at any time during the drying process, and steps can be skipped arbitrarily. It has a pre-freezing function and does not require an external pre-freezing warehouse, which solves the risks of material movement liquefaction and contamination. It has process adjustment, curve temperature control, and temperature and vacuum control adjustment functions to meet the process requirements of different materials.

[0053] When the food needs to be crushed, the food is placed in the freeze dryer, and after the food is freeze-dried, the freeze-dried food is put into the moving shell 4, and then the moving shell 4 is pushed to move the food inside towards the grinding plate 3. In the process of moving, the first triangular block 15 is separated from the slide rod 11, and under the action of the elastic force of the first telescopic spring 13, the pressing plate 12 moves vertically downward and presses the food. When the food contacts the plurality of grinding blocks 44 on the grinding plate 3, the food will be divided into a plurality of fine particles.

[0054] At the same time, the moving shell 4 moves, and the scraper 5 inside the cavity is moved horizontally through the connecting rod 6. When the moving shell 4 is about to move to the leftmost end of the base 1, the scraper 5 will contact the second triangular block 19 and drive the second triangular block 19 to insert into the second transmission hole on the surface of the positioning rod 17. Under the action of the inclined surface of the second triangular block 19, the positioning rod 17 moves vertically downward, and one end moves out of the positioning groove. The first spring rod 18 is compressed. At this time, the locking of the first rack rod 7 is released, and then the first rack rod 7 is moved at the same time. The plurality of first straight gears 8 are driven to rotate by the first rack rod 7, and the grinding plate 3 is turned over in the mounting hole by the rotating shaft 2. Until the moving shell 4 moves to the leftmost end of the base 1, the grinding plate 3 is turned over by 180°. At this time, the ground food on the upper surface of the grinding plate 3 will enter the cavity and fall off from the grinding plate 3 under the action of its own gravity, so that the ground food and the unground food are separated, avoiding the ground food from interfering with the unground food and the grinding plate 3, thereby improving the grinding rate.

[0055] When the moving shell 4 moves to the left end of the base 1, the scraper 5 will pull the pull rope 27, and when the pull rope 27 is straight, the horizontal rod 26 is pulled vertically downward through the guide wheel 28, thereby driving the supporting plate 24 to move vertically downward. When the moving shell 4 moves to the leftmost end of the base 1, the supporting plate 24 just contacts the inner bottom wall of the cavity, and under the action of the second spring rod 32, one end of the trapezoidal block 33 is inserted into the lock hole, thereby locking the horizontal rod 26. The supporting plate 24 can be locked at the lowermost end of the guide hole, and the movement of the supporting plate 24 is automatically realized, thereby facilitating the pushing of the ground food onto the supporting plate 24. The structure is compact and easy to operate.

[0056] Then the movable shell 4 is driven to move back. At this time, the scraper 5 will push the ground food that falls into the cavity toward the rectangular block 21. When the scraper 5 is about to move to the rightmost end of the cavity, the scraper 5 will first contact the push rod 20 fixedly installed at the other end of the first rack rod 7, and drive the first rack rod 7 to move in the other direction through the push rod 20, and drive the positioning rod 17 to move into the positioning groove until the positioning rod 17 is inserted into the positioning groove under the action of the elastic force of the first spring rod 18. At the same time, it will drive the grinding plates 3 in the multiple mounting holes to rotate 180° in the opposite direction, so that the multiple grinding blocks 44 on the grinding plate 3 return to the upper surface of the base 1 again. The grinding plate 3 is repeatedly flipped through the reciprocating movement of the movable shell 4.

[0057] When the scraper 5 contacts the push rod 20, it will continue to drive the top block 34 to move into the lock hole. At the same time, the scraper 5 will push the ground food into the guide hole and accumulate it just above the support plate 24. When the top block 34 is inserted into the lock hole, it will push the trapezoidal block 33 out of the lock hole, and the second spring rod 32 will be compressed. At this time, the locking assembly releases the lock on the cross bar 26, and then under the action of the elastic force of the second telescopic spring 31, the vertical rod 23 is driven to move vertically upward. Since the sliding connection points of the moving block and the support plate 24 are both located on the support plate 2 4 center line, and then when driving the supporting plate 24 vertically upward, the supporting plate 24 will rotate until the supporting plate 24 contacts the top rod 25 fixedly installed on the vertical rod 23, thereby ensuring that the supporting plate 24 is in a tilted state. In the tilted state, the food above the supporting plate 24 approaches the side with the filter holes in the guide hole. When the food passes through the filter holes, the food that meets the coarseness and fineness standards will pass through the filter holes and be collected in the collection box 35, realizing the function of automatic unloading, while the food that does not meet the standards will move upward with the supporting plate 24.

[0058] When the movable shell 4 moves to the rightmost end of the base 1, the first triangular block 15 will be inserted into the first transmission hole opened by the slide rod 11. Under the action of the inclined surface of the first triangular block 15, the slide rod 11 will drive the pressure plate 12 to move vertically upward, and the first telescopic spring 13 will be compressed until the pressure plate 12 moves to above the guide plate 22. When the support plate 24 continues to drive the food to move upward, the support plate 24 will contact the limit rod 29. Under the limit of the limit rod 29, the support plate 24 and the movable block will slide relative to each other, and the support plate 24 will rotate in the other direction, so that the food above the support plate 24 will slide onto the guide plate 22 and slide along the guide plate 22 into the movable shell 4, and the ground food can be automatically put into the movable shell 4 again. Through the repeated movement of the movable shell 4, the food is ground multiple times until the food is ground to the required coarseness.

[0059] In the process of the support plate 24 driving the food to move upward, the two ends of the rotating rod 37 move vertically upward in the two slide grooves 39 respectively, and at the same time, the rotating rod 37 is driven to rotate by the second spur gear 40 and the second rack rod 41, so that the rotating rod 37 drives the multiple curved plates 38 to rotate. The rotation of the curved plates 38 drives the food above the support plate 24 to rotate continuously, preventing the food with larger particles from staying on the side close to the filter hole, blocking the other food with the required coarseness and fineness from passing through the filter hole, so as to facilitate the food with the required coarseness and fineness to pass through the filter hole.

Any technician familiar with the technical field, within the technical scope disclosed by the present invention, who makes equivalent replacements or changes based on the technical solution and inventive concept of the present invention, should be covered by the scope of protection of the present invention.
